## What does nylas tui do?

The nylas tui command opens a full-screen terminal interface for managing email, calendar events, and contacts. Navigate your inbox with keyboard shortcuts, read and reply to messages, and switch between accounts — all without leaving the terminal. The TUI renders rich email content and supports vim-style navigation.

## Usage

```bash
nylas tui
```

## Flags

| Flag | Description |
| --- | --- |
| --json | Output as JSON |
| --no-color | Disable color output |
| --verbose(-v) | Enable verbose output |
| --config | Custom config file path |
| --help(-h) | Show help for the command |
| --limit | Limit results (most list commands) |
| --yes(-y) | Skip confirmations |
| --refresh | Refresh interval in seconds |
| --theme | Color theme (k9s, amber, green, apple2, vintage, ibm, futuristic, matrix, norton, or custom) |

## Examples

The nylas tui command opens a full-screen terminal interface for managing email, calendar events, and contacts.

### Launch the terminal UI

```bash
nylas tui
```

### Launch with verbose logging for debugging

```bash
nylas tui --verbose
```

## Example output

```text
Launching Nylas TUI...

  Connected as alice@example.com
  Navigate: j/k move, enter open, : command, / filter, ? help
  Press Ctrl+C to quit.
```

## Troubleshooting

### TUI shows blank screen or garbled output

Ensure your terminal supports 256 colors and is at least 80x24 characters. Try a different terminal emulator if the issue persists.

### No emails shown in TUI

Run `nylas auth whoami` to verify an account is connected. The TUI requires an active grant — run `nylas auth login` if needed.
